Fuel line

I was about to plumb my fuel line and was curious what size I should use for the hardline. I have a basically stock 292 Y-block running a electric fuel pump, nothing fancy. I know it has been covered before but any feed back would be appreciated.
Thanks

 

5/16 will be more than adequate

 

i used 3/8 on my 272 y block

 

5/16" will be more than enough.

 

5/16" is plenty, but if you think you might make some performance upgrades someday, maybe go for 3/8".
